They've already developed a lens-with-LED prototype that's powered by 330 microwatts of wireless radio-frequency power, and believe the lenses could also be used as biosensors to deliver body chemistry readings (including blood sugar levels). "What we've done so far barely hints at what will soon be possible with this technology," says Dr. Babak Parviz.

"We already see a future in which the humble contact lens becomes a real platform, like the iPhone is today, with lots of developers contributing their ideas and
inventions."
